* String-hacks. Use these macros to stifle warnings on (presumably) correct
|
|
* uses of strcat, strcpy and sprintf.
|
|
*
|
|
* By the way -
|
|
* A fundamental limitation of the interfaces (and frequent issue in bug
|
|
* reports using these functions) is that sizes are passed as unsigned values
|
|
* (with associated sign-extension problems), limiting their effectiveness
|
|
* when checking for buffer overflow.
